DESCRIPTIONdwm is a dynamic window manager for X. It manages windows in tiled, monocle and floating layouts. Either layout can be applied dynamically, optimising the environment for the application in use and the task performed.
In tiled layouts windows are managed in a master and stacking area. The master area contains the window which currently needs most attention, whereas the stacking area contains all other windows. In monocle layout all windows are maximised to the screen size. In floating layout windows can be resized and moved freely. Dialog windows are always managed floating, regardless of the layout applied.
Windows are grouped by tags. Each window can be tagged with one or multiple tags. Selecting certain tags displays all windows with these tags.
Each screen contains a small status bar which displays all available tags, the layout, the title of the focused window, and the text read from the root window name property, if the screen is focused. A floating window is indicated with an empty square and a maximised floating window is indicated with a filled square before the windows title. The selected tags are indicated with a different color. The tags of the focused window are indicated with a filled square in the top left corner. The tags which are applied to one or more windows are indicated with an empty square in the top left corner.
dwm draws a small border around windows to indicate the focus state.

CUSTOMIZATIONdwm is customized by creating a custom config.h and (re)compiling the source code. This keeps it fast, secure and simple.
BUGSJava applications which use the XToolkit/XAWT backend may draw grey windows only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the environment variable AWT_TOOLKIT=MToolkit (to use the older Motif backend instead) or running xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D or wmname LG3D (to pretend that a non-reparenting window manager is running that the XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable _JAVA_AWT_WM_NONREPARENTING=1.
GTK 2.10.9+ versions contain a broken Save-As file dialog implementation, which requests to reconfigure its window size in an endless loop. However, its window is still respondable during this state, so you can simply ignore the flicker until a new GTK version appears, which will fix this bug, approximately GTK 2.10.12+ versions.
